2.0 engine will not slow down to idle,must be placed into neutral to slow down or stop
Check for vacume for leaks,they will make you rev up like that.
vac leaks, bad IAC, or TPS
I concur about the IAC (Idle Air Control). Before you rush out to replace this part, take it off, clean the carbon build-up out with brake cleaner or mild solvent & clean rag. I did this to my 2000 Dodge Neon and the idle is acting perfectly normal once again.
